then Xine on the core seems to eventually crashes yet if I view the content on the core there is (not the mds) theres no poblem this is 10.04 the core has 4gigs of ram and 3 core processos using kernel 2.6.38. when the video runs on the md the sound is always like 2 - 3 behind; but the video and sound is pretty smooth.

my mds are using vdpau and HD content from Mythtv (OVA TV) and media stored on the core (MKV H264 1080p video) works grreat. The problem I have is connecting HD content to the HDPVR to stream to other areas. like roku -> HDPVR -> core -> mds

on the core the video look great, but to the md it doest. it even freezes xine on the core to the point where i have to restart the core.

As I said in channel, this is an issue with Xine not really doing much to ensure that the data gets to the target media directors in time. The whole slave:// streaming method from fifo devices is something of a hack, and while it worked well for the old PVR-150/250/500 devices, it seems to fail miserably with the HD-PVR, we need to find another option that can be realistically used, and if there are any coders who would like to dig in to help, that would be GREAT, as I am currently embroiled between fixing the Telecom system and working on the Weather plugin.
